Dr. Ruaidhrí Neavyn:

They could have, but it was queried. I have asked people these questions. The position would be that the order was signed off and approved by the most senior officer in the institution. It was queried and that person indicated it was authorised to sign off. If one is putting a query to the senior financial officer, one is put in a very difficult position if one is being told by that senior financial officer that everything is in order to be signed off.
